The VS150 is a Compact Czerny Turner spectrograph with excellent speed, spectral range and spectral resolution with software control of slit size, input f#, order sorting filters, grating angle and dark exposures. For VUV operation the spectrograph has a UHV window and laminar flow purge system, which allows operation down to the window short wavelength cut-off (112 nm for MgF2). The spectrograph employs interchangeable gratings and can interface to a UHV chamber or used on a benchtop in any orientation at the end of a 5-meter cable. Accessories include a built-in spectral calibration lamp, a multi-spectral flat-light source and low-cost accessories such as telescopes, vacuum adapters, flow controllers.

Front 2.75 in flange can be attached to UHV chamber. Spectrograph is isolated with MgF2 window in vacuum adapter. Purge can be dry N2, Ar, or He.

The Spectrometer can be removed from a vacuum chamber without breaking vacuum. This allows bake out of the UHV chamber above the non-operational limit of the spectrometer.

Software drivers and demonstration programs are available for Visual Basic, Delphi, LabView and C++. Interfacing can also be accomplished using the spectrograph virtual COM port. This allows low-level programming with ASCII string commands.
